Benefits of technology

Enables cost-effective automatic manufacturing of Ethernet transmission circuits with integrated signal coupling, DC isolation, and surge protection, reducing production costs and enhancing device reliability.

Problems solved by technology

However, for current Ethernet devices on the market, transformers used therein is manufactured manually, which leads to a rather high production cost.
In addition, the Ethernet devices on the market do not have a surge protection function to prevent voltage surges generated by lightening strikes or static electricity in the environment or by switching on and off of the power source.
